TYPEVRITING MACHINE.

Application filed December 5, 1912.

Specification of Letters Patent.

rammed oct. c, 1era. Serial No. 735,107.

vention as described herein are included within the generic invention which isl described and claimed in'Letters Patent No. 1,053,919, granted Feb. 18, 1913, upon my eo-pending application filed April 20, 1908 Serial No. 428,212.

(.)ne of the objects of my general invention is to supply the operator of aA typewriting machine with progressive indication ofthe 'distance from the current printing point to the bottom end of the sheet, or to another point on the sheet, and this without preliminary care onv his part, automatically.

Additional objects erator with further indicating means, comprising improved means whereby such types as may be desired of visual, audible and mavchine-lock signaling devices may be ein-, `ployed to indicate the arrival of the sheet into predetermined printing positions.

Featuresv of the present branch or division of the invention include a novel form of intermittently-actuated paper-feeler which entirely rctractsfrom the usual path of the entering sheet with each movement of the space-lever, thereby facilitating` the entering of the'sheet into the machine and the backward actuation thereof from any sheet-position; a novel form of sheet-controlled lspace lever-actuated drive for the central perative member, whereby the indices used may be increased in size, if desired, and affordand various novel constructions and combinations of elemdnts adapted to render thefinvention more useful in practice, as will be hereinafter eX- plained.

In the draWings,-Figure 1 is a View in end elevation of portions of a typewriting machine` showing an embodiment of my invention applied thereto.l Fig. 2 is a plan view ofportions of the same. F ig. 3 is a View partly in section of a detaily of Figs. 1 and 2. F 1g. 4 is a cross-section .of certain l parts on theline ii. Fig. 1,.

are to supply thel opvluble' drum 6 Fig. isan end eley'ation partly in section of a modification. Fig. is a cross-section of portions of the same on the line 6-G. F ig. 7 is a front `view of certain parts shown in Fig. 5, but with the addition of the ends of the car riage-frame in section supporting structure thereon.

rl`he stationary main frame et' a 1tj-*pewri'ting machine is indicated at 1, vand at 2 the end frames of the usual transversely movable carriage, in which is journaled a platen arbor 13 having ixedlyattached thereon a platen- ;roll for advancing the sheet, the4 platen beingr rotated by usual line-spacing mechanism comprising in this case a space-lever 11 journaled on pin 12 carried by bracket 552 on said carriage-frame. The space-lever is here shown as havingr an arm 1b" bearing a pln 17 on which is journaled a pawl 18- adapted to coperate witlra ratchet-wheel 18 attached at the end of the platen, and is shown as returned into initial position by a coiled spring 97, one end of y'hich is at tached to bracket 82 and the other end of which engages with said space-lever- The usual lpaper-table for the support and guidance of the enterin sheet is indicated at 8, and the usual typears at 7 8, connected in usual manner with the key-lever 61. Other typewriting parts not necessary to be shown may be as in practice. As thus described the parts are old inthe art; they are or may be of any approved type.

Referring more particularly to the embodiment of theinvention represented in Figs. 1 to 4', I employ an operative member and operating means therefor preferably conetructed as follows :'-The 'opera-tive inexnber, in this case having the form of aV revo- (Fig. 44f), is journaled upon platen arbor 13 adjacent to platenhead 39. Attached upon the face wall of said drum is a series of ratchet-.teeth 5. The face wall of said drum 6 is supplied with one or more threaded holes 36', into any one of which a projection 36 is adapted tn be screwed, said' projection being thereby angularly adjustable uponA said operative member or drum. The' face wall of said drinn is also supplied with the threaded holes ed', into anyone of which projection 40 maybe screwe l,`said projection heine thereby also angularly adjustable upon tie drum. Said face wall of and the npstanding cli-unna colored signaling segment 6b as simultaneous orcoordinate `viththat 'oi the veo Attached to said post is one end of a helical Vexpands radially into Jrictional engagement 'vent thelover-Winding of the spring.

drum, a position-stop 35 on carriage-frame vto be actuated past the stop Operative member or drum the drum hasa central opening into which projects a split post 27, carried on frame 2,

spring' 25, the other end beine attached to a resilient friction band or split-ring 7 that with drum The purpose of the frictionling;` is to provide for slipping so as to pre- Jouris a hinged naled on carriage-frame 2 at 84 jects into the path of projection 86 on the 2 serving` to limit the movement or" said hinged stop in a backward direction. Spring 25 tende to rotate drurn 6 in a bachlWard direction so as to bring projection 36 against hinged stop 31 and said stop against positionstop 35, as shown in Fig. 1( Stop 81 is hinged in order to permit projection 36 in `contirnned forward actuation oi drum 6', said stop seplwith said teeth, and

arating' from osition-stop .35 `in such case. A down-stan ing portion 'p83 of carriageframe 2 bears a laterally-projecting. pin 73 on which is journaled'a datent 7d Weighted at ,to cause tooth 76 thereon to 'tend to press toward rat' het-teeth 5, and having an upwardly-extending curved portion 77, the purpose of which will be explained later. Drum 6 is an index-carrieigand is supplied with indices. A visual signaling means is also' calledlinto. 'operation through saif o paper being attachedthereon in any desired angular position as' by means of paste. shield-pointer 34 is attached upon laterallyextending pin 96 on carriage-'frame 2 in suitable position to cooperate with. said indices and signaling segment on said drum. 6l in thisk em- Working actuation that is bodiment is given sheet-advancing platen by one of the parte ot' the typewriter mechanism, preferably the space-lever, undei1 the control of `a j'iaper-eeler pressed intermittently against the sheet by one of the parte oi the typewriter mechanism, preterabl the space-v lever also, the space-lever in t is case being vrod 19, `pin lever results in the agent employed in Aadvancing the platen and having in addition to its platen-advancing function the' double function aforesaid. Said actuating and controlling means are described thus: The'ends of, carriagerame 2fare constructed with upstanding portions 81 in which are journaled the ends' of the laterally-extending roch-shaft 2d. 'lixeclly attached upon said shaftie an arm 22, said arm being connected throughfpin 23 there on,l `connecting-rod` 19, and pin 17 on armi 16,. With space-lever'11,v pin 23 aforesaid being suiiciently loose in its bearing; in rod 19 to permit the play ofl parte. Fixedly atl tachedfup'on said rock-shaft 2O near thel other end is an arm 26 having thereon an inwardly-extendingpin 29 upon which is journaled an elbow-lever 30, one arm of which has va slot 33. The other arm of said elbow-lever is turned-in so as'to extend inwardly over ratchet-teeth 5. The turned-in portion is shaped as a pavvl 32,

' has a position between said teeth and the curved portion 77 of detent 74; so that ivhen inovcd away roin said teeth it will engage with said curved pontion 77 and move said detent away from to cooperate teeth 5 also, Loosely journaled upon rockm j shaftv 20 between Xedly-attached arrn 26 and a iiXedly-attached collar 24 is a sleeve 21, bearing near one end a iixedlyattached arno 37 and near the other a iXedly-attached paper-ieeler 28. Arm 37 carries an out- Wardlyhextending pin 38 that projects into slot in elbowlever 30 'before named. Pa.per-'feeler 28 is adapted to enter slot 4.- in paper-table 8 Pawl 32 tends to be held against ratchet-teeth 5 by its ownvvveight and that of arm 37 and paper-feeler 28.

This portion of the mechanism operates as follows: The paper-sheet atig. 1) is" entered into the niachine along paper-table 8 and advanced into printing position.

Upon l the completion of the iirst line of Writing, the sheet -ie advanced by the platen under the'l actuation of space-lever 11, all in usual manner. The operation of the space-lever rocks shaft 20 through pin 17,

l 23 and arm 22, thereby reciring arin 2G downwardly, and through pin 29, pavvl 32 on elbow-lever 30, and ratchetteeth 5, giving actuation to operative menr her or drum G. The saine action is communicated from elbow-lever 30 to, sleeve 2i through arm 37, pin 38 thereon, and slot- 33, thereby actuating phper-,feeler 28 towardthe paper-path. Ae the sheet lies over slot e in the paper-table, the paper-eeler is unable to enter the slotbut is detained vby the sheet.' Sleeve 2l' and arm B7 are thereby prevented Jlfrom con'iplete rocking nievement, Further movement of arm 26 down- Wardly under the actuation oft the space vthe lifting of pawl 32 away from ratchet-.teeth 5, one arm of elbow-lever 30 being acted upon by the novvstationary pin 38. Still further movement of said arm 26 causes pawl 32 to lift det/ent 7% away from said` ratchet-teeth likewise, thronffh engagement with the curved. portion i7 ther-ectn `rlliereupon drum 6,, neither driven by pawl 32,1101 detained against the tension of spring 25 by datent-tooth 76,ie rotated hacirtvardlv by saidspring jection 3G meets stop 31 land said stop holds said drum from further backward rotation.;V This position of the drum niay be designated" its lcjonstant or predetermined starting posi,-`

tion, and into this position the, drum must moci'sheet in the nath of the a er-feeler 1 i a for such will be the action of the parts forl each stroke of the space-lever during the contrrril of the paper-feeler by the sheet. 5 llventually however the paper-sheet will be advanced until the vbottom end thereof passes from over slot 4. rlhe next succeeding stroke of the space-lever will result in the rotative actuation of drum 6 by pawl E@ Si? and the detention thereof by detent tooth` '76 in advanced position, since paperfecler is now free to ent-er slot 4, and pavvl 32 and tooth 76 are not actuated thereby out of engagement with ratchet-teeth 5. i5 Such advance will bring an index upon drum 6 from behind shield-pointer 34 into indicating position. The next stroke of the space-lever will bring a second index into indicating g@ the sheet. The indices may be as desired: I prefer to use a series ot downward-count `ing numerals indicating the number of linespace actuations between the printing-point and the bottom end on the sheet a given distance therefrom;

By using a. drum 6, said drum can be rotated if desired at a greater speed and through a greater angle than the platenso as to render a so larger indicating surface available for each index in the series. nannerals are used, as in the drawings, it may sometimes be found desirable te change the angular position of pin- 36 on drum 6, 35 since the number of feed-movements between the printing point and the end of of the advance of the sheet by each feed movement. rlhat 1s to say,` it the sheet 1s 4c advanced a sinele line for the reed-movement, the first index brought linto indicating position by the working movement of drum 6 will be a higher numeral than if the feed isby double-line advances or by triple-line sa advances. The seats 36 therefore are provided so as to adjust the constant starting position of drum 6 according 'to the of the feed movement. If the :feed is by single lines, index i8 may be the one rst 50 brought into indicating position, indicating that eighteen. feed movements will elapse before the end of the sheet is reached; if by double-line advances, index 9 may be the .tirst to be brought into indicating position,

55 indicating that nine feed movements will @lapse before the end of the sheet is reached ;v

:an-:lit b vtrii'ilc-line advances, the index 6. indicating that six feed movements will elapsc. 'The indices, wl'xatever they may be, n heurter be used if desired with all tei-,ds without adjusting pin 36 angularly on drum 6, Color-segment 6 is used indef i'lr ci' the indices or in connection "f h; at the predetermined sheet-posil` e5 non is brought into View by drum 6 from y pin- 44,

position; and so on to the end of of the sheet -or a pointl pawl-andratchet actuation for lf downward-counting the sheet will vary according to the extent `Supported by t extent behind shield-pointer 34,*thereby giving the operator a visual signal at any desired distance from the end of the sheet. i

Additional indicating means are provided for as follows: Carriage-frame 2 bears an inwardly projecting pin 43, upon which .is journaled elbow-lever -41. One end of said elbow-lever projects into the path of projection 40 on drinn 6. Said lever bearsa on which is journaled link supplied with a handle 47 and an elbow trip-slot 48. Pinl 49 on carriage-frame 2 has journaledy thereon an arm 50, and it' will be understood that a similar pin at the other end of the carriage-frame has journaled thereon a similar arm, the two arms being connected by theflaterally extending bail rim 5l so as to form a rocking bail-piece. Pin 46 on arm 50 projects into trip-slot 48 before named. A rock-shaft 53 is journaled at either end in main frame 1. On said rockshaft about midway of its length is a fixedly-attached arm 52 adapted to engage With bail-piece 5l universally, in every lateral p0- sition of the carriage'. Near the end of said rock-shaft is a ixedly-attached arm 54. A rock-shaft is also journaled at=either end in said main frame, ixedly attachedto which at either end is an arm 61.

l are connected by a transversely-extending locking bail-rod 62 in such manner that when shaft 60 is rocked, rod 62 is caused to take a position under the lock-projections 63 on the key-levers 64 so that said key-levers can no longer be depressed about their axis 65 and the printing types 79 on the typebars 78 can no longer be used in printing.

One arm v61 is connected through pin 59 thereon and rod 56 with pin 55 on arm 54.

A spring 57 attached' at one end to inwardlyprojecting pin 58 on frame l and at the other to arm 54 tentlsxto hold' the said arm 6l against position-stop 66 bail-rod v62 clear of lugs 63. A bell 7l is he central pin 72 in the phth of bell-hammer 70. Said hammer is carried on a light spring-rod 69 that radiates from hub 67 adjustably attached upon shaft 60 by means of' set-screws 68.

This portion of the mechanism operates as follows: Pin 40 on drum 6 at the predetermined time is-brought into engagement with lever 41 in its path lby the Workingmovement of .said drum, rocking' said lever, and through pin 44, rod 45, and pin 46 rocking bail 5l against arm 52. Shaft 53 is thereby rocked, and through arm 54, pin 55, rod 56, pin 59 and arm 61, bail-rod 62 is moved under lock-projections'G, thereby rendering the printing `mechanism of the typewriter inoperative for use. Through the said arm 61 the same action rocks shaft 60, hub 67 thereon, and spring-rod 69, causing bellhammer 70 to strike dible signal.
